APPLICATIONS

The Bendix K070951 ATR-6 Traction Relay Valve is designed for selected heavy-duty commercial truck air brake systems requiring a compatible 12V automatic traction relay valve.

Potential applications include:

• Heavy-Duty Commercial Trucks

• Semi-Trucks and Highway Tractors

• Kenworth Trucks with Compatible ATC Systems

• Commercial Vehicles Equipped with Bendix ABS/ATC

• Air Brake Systems Requiring an ATR-6 Traction Relay Valve

Exact vehicle compatibility depends on the original valve part number, air port configuration, mounting specifications, and ABS/ATC system requirements.

FUNCTION

The Bendix ATR-6 Traction Relay Valve combines pneumatic service brake relay operation with electronically controlled traction management.

During normal braking, the valve helps deliver compressed air to the appropriate brake circuits. During automatic traction control operation, the integrated solenoid supports controlled brake application to reduce excessive drive-wheel spin.

A worn, damaged, or failing ATR-6 traction relay valve may cause symptoms such as:

• Air leakage around the valve or exhaust

• Delayed or inconsistent brake response

• ABS or traction control warning lights

• Reduced traction control effectiveness

• Electrical solenoid or pneumatic valve fault codes

• Improper air pressure delivery during braking

WHY REPLACE AN ATR-6 TRACTION RELAY VALVE?

A malfunctioning traction relay valve may interfere with service brake operation and automatic traction control performance.

Replacing a defective valve with the correct Bendix K070951 ATR-6 component helps restore intended air pressure regulation, proper pneumatic relay operation, and reliable ABS/ATC system functionality.

Proper brake system operation is essential for commercial trucks operating under heavy loads, on highways, and in changing road conditions.
